This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction, refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials. [1] [2]
Basic insulation is any material added to protect a user from accidental contact with energized parts. Supplemental insulation is rated to withstand 1500 volts AC. Double insulation is a design concept where failure of one insulation system will not expose the user to a shock hazard due to the presence of a second independent layer of insulation.
The insulation bonds the service pipe and the casing together. The main purpose of such pipes is to maintain the temperature of the fluid inside the service pipes. Insulated pipes are commonly used for transport of hot water from district heating plants to district heating networks and for distribution of hot water inside district heating networks.
Asbestos insulating board (AIB), also known by the trade names Asbestolux and Turnabestos, is an asbestos-containing board formerly used in construction for its fire resistance and insulating properties. [1]
During the 1950s, the standard U.S. Army motorized 203 mm (8.0 in) artillery piece was the M55, based on the chassis and the turret of the M53 155 mm self-propelled gun, which used some components from the M48 tank.
Two ships of the Royal Navy have been named HMS Nasturtium: . HMS Nasturtium (1915) was an Arabis-class sloop launched in 1915 and sunk in 1916 HMS Nasturtium (K107) was a Flower-class corvette ordered as La Paimpolaise by the French Navy she was taken over in 1940 and renamed.
Pipe insulation made from rigid Phenolic, PIR, or PUR foam insulation is common in some countries. Rigid-foam insulation has minimal acoustic performance but can exhibit low thermal-conductivity values of 0.021 W/(m·K) or lower, allowing energy-saving legislation to be met whilst using reduced insulation thicknesses.
